File::Spec -- portability, damn I like it
Except when it makes your life hell due to incompatability with other modules, as you have to regex everything into Unix style to get modules like File::Basename to work with it. Or try using with a file upload from an OS that isn't the same as the server. As a consequence I now avoid it like the plague.
